小程序之数据储存

详细请参考:
https://developers.weixin.qq.com/miniprogram/dev/api/storage/wx.setStorageSync.html

存:
onLoad(){
      wx.setStorage({
         key: ‘goods‘,
         data: JSON.stringify({
"goodsName" : "三只松鼠","price" : 300
}),
      })
   }

取:
onLoad(){
      wx.getStorage({
         key: ‘goods‘,
         success: function(data) {

            console.log(JSON.parse(data.data));
{goodsName: "三只松鼠", price: 300}

         }
      })
   }

删除( 删掉的是key值 ):
onLoad(){
wx.removeStorage({
         key: ‘goods‘,
         success: function(res) {
            console.log(res);
            //{errMsg: "removeStorage:ok"}删除成功返回ok
         },
      })
}
